By Du definition, I guess I have an assault rifle.

[Straw Man]

90. Single-action? Double-action? Are you talking pistols or rifles?

Double-action means the trigger both cocks and releases the hammer. Single-action means that the trigger only releases the hammer; the hammer must be cocked independently of the trigger, either by the rearward movement of the bolt after firing, as with semi-autos, or by the manipulation of a lever, pump, or bolt handle, as with manual repeaters.

There's no such thing as a double-action rifle, except for a few oddballs that are based on revolver actions. As for pistols, are you aware that there are plenty of double-action semi-auto pistols? Not to mention DA/SA, which are both?

Then there are double-action revolvers, which actually function in a manner similar to semi-auto firearms (one shot per trigger pull), whereas single-action revolvers must be cocked for every shot (think cowboy guns).

Either you don't know what the terms double-action and single-action mean, or there's some huge part of your reasoning that is escaping me.
